## Detailed Description

Keep One in N Block Control Class

The Keep One in N block has two modes: sample mode and packet mode. In sample mode, the first sample is kept and then N-1 samples are dropped. Packet mode is similar to sample mode, except a packet of samples is kept and then N-1 packets are dropped. The packet size is determined automatically.

## Member Enumeration Documentation

## ◆ mode

| strong

Enumerator
SAMPLE_MODE |
PACKET_MODE |

## Member Function Documentation

## ◆ get_max_n()

virtual size_t uhd::rfnoc::keep_one_in_n_block_control::get_max_n | ( |  | ) | const
| pure virtual

Get the maximum supported value for N

Get the maximum supported value for N for all channels

Returns
  The maximum supported value for N

## ◆ get_mode()

virtual mode uhd::rfnoc::keep_one_in_n_block_control::get_mode | ( | const size_t | chan = 0 | ) | const
| pure virtual

Get the current mode

Get the current mode (sample or packet mode, see mode enum)

Parameters

  chan | The block channel

Returns
  The current mode

## ◆ get_n()

virtual size_t uhd::rfnoc::keep_one_in_n_block_control::get_n | ( | const size_t | chan = 0 | ) | const
| pure virtual

Get the current value of N

Get the current value of N

Parameters

  chan | The block channel

Returns
  The current value of N

## ◆ set_mode()

virtual void uhd::rfnoc::keep_one_in_n_block_control::set_mode | ( | const mode | mode,
|  | const size_t | chan = 0 )
| pure virtual

Set the mode

Set the mode. There are two modes, sample mode (0) and packet mode (1). In sample mode, the block will keep 1 value and then drop N-1 values. In packet mode, the block will keep 1 packet and then drop N-1 packets.

Parameters

  mode | The mode of the block
  chan | The block channel

## ◆ set_n()

virtual void uhd::rfnoc::keep_one_in_n_block_control::set_n | ( | const size_t | n,
|  | const size_t | chan = 0 )
| pure virtual

Set the value of N

Set the value of N. See set_mode() for how the value of N is interpreted depending on the mode.

Parameters

  n | The number of samples or packets to drop (minus one)
  chan | The block channel
